GEORGE SYMES, OF MASON CITY, IOWA.

RAILWAY CONSTRUCTION.

Application filed August 12, 1912.

To all whom it may concern:

Be it known that I, GEORGE SYMEs, a citi- Zen of the United States, and a resident of Mason City, in the county of Cerro Gordo and State of Iowa, have invented an Improvement in Railway Construction, of which the following is a specification.

My invention is an improvement in the class of railways in which the running rails rest on arched metal chairs or supports that are in turn secured to transverse metal ties.

The invent-ion is embodied in the construction and connection of the chairs or rail supports and the transverse ties connecting them.

In the accompanying drawing Figure 1 is a plan view of a section of a railway in which the rail supports and ties are constructed and connected in accordance with my invention. Fig. 2 is a vertical section on the line 22 of Fig. 1. Fig. 3 is a vertical section on the line 3-3 of Fig. 1. Fig. 1 is a perspective view of the arch and cap plate of which the chairs or rail supports are formed, the two parts being shown separated. Fig. 5 is a cross section on the line 55 of Fig. 1. Fig. 6 is a perspective view of a washer. Fig. 7 is a perspective view of a rail clamp.

The railway rails 1 are of the usual construction and rest and are secured upon double chairs or supports 2, 3, which in turn rest upon, and are bolted to, flat tops of transverse metal ties 4. The latter are T- shaped in cross section, the flat side being uppermost and the lengthwise rib or web lying embedded in the earth, as shown in Fig. 2. This construction of tie combines the elements of maximum lightness, strength, and economy of construction, besides being aarticularly efficient in preventing creeping or longitudinal displacement of the rail supports. The construction of the ties further provides a fiat top for support of the chairs 2, 3, and for convenient and secure attachment of the same to the ties.

The chairs are composed of the parts 2, 3see especially Figs. 3 and a. The upper side of the part 2 is convex or curved, and the under side flat, and between these two parts extends a rib or central web 2see Figs. 4 and 5. This construction combines maximum strength, rigidity, and lightness. The arches 2 are arranged in pairs, one on Specification of Letters Patent.

each tie 4;. The convex caps 3 extend from one arch 2 to the other, as will be understood by reference to Figs. 1 and 2, thus forming what may be termed a bridge that spans the distance between two adjacent ties.

A single screw-bolt 6 is applied on each side edge of the arch and cap and also passes through the lateral flange of the adjacent T-shaped tie, as shown in Figs. 2 and 3. A beveled washer 7see Figs. 3 and 6-is applied between the nut of the bolt 6 and the curved edge of the cap 3. The ends of the arch 2 are provided with notches 8see Fig. %to receive the said bolt 6, so that the latter prevents the arch shitting its position and yet providing for convenient attachment and detachment of the arch relative to other adjacent parts.

It will be seen that the rail supports formed of two parallel arches 2 and a connecting convex cap 3 combine great strength, rigidity, and lightness and may be constructed at small cost and quickly and easily set in place and secured together. The rails 1 traverse the caps 3 lengthwise, the latter being slightly flattened to provide a secure rest for the base of the rail. The cap plates 3 rest upon the ballast and form an umbrella-like protector for the same.

Clips or clamps 9see Figs. 1, 3, and 7- are applied for holding the rails against lateral displacement, the same being secured by screw-bolts 10 passing through the cap at several points, as indicated particularly in Fig. 1.

What I claim is 1. The combination with adjacent transverse ties, of rail supports secured on and connecting the same and comprising arches having a convex top and fiat base, and a trough-like cap resting on the adjacent arches and secured thereto and to the ties, as described.

2. The combination with adjacent transverse ties, of rail supports secured on and rigidly connecting the same and comprising arches having a convex top and flat base, also end not'ches and an arched cap applied to and resting upon adjacent arches, and screw-bolts passing through the cap, the notches of the arches, and the ties, as described.

3. A railway comprising rails proper, chairs upon which the same rest and to which they are bolted, said chairs consisting through the aforesaid cap and arches and of narrow arches arranged transversely of through the lateral flanges of the ties, as dethe rail and convex caps resting upon adscribed.
